Any motorplan issues if you go away from the runflats or go oversize??

Dealer remarked that switching to run-flats or altering width would affect motorplan, as well as potential problems with insurance companies.

Too much admin to worry over and I appreciate the safety aspect of run-flats. The rears were replaced with OEM Bridgestone Potenzas, R3k each. They had 30,000kms and could have gone a few more if need be.
